Thanks very much Red,
I appreciate your help and will keep you up to date on its progress. At this point am still waiting for the smaller plans to see if I am better of scaling them up for the fuse or doing a plug from 3-views and molding from that.
Another question if you don't mind, I see the SD6060 is not a fully semetrical profile, is this better for any reason? As a newcomer to the racing scene I have yet to learn these finer details, I would have thought better penetration from no lift, maybe not so. About the only thing it looks I was on the right path of is I was aiming at around 10% of the wing cord for wing depth.

Hi Byron,
A fully symmetrical profile must fly at some positive AoA to produce lift. Lift produces drag. A semi symmetrical section can provide an equal amount of lift but with less drag and will usually turn harder. You see the symmetrical airfoils doing pretty well in Q-500 applications, but they have the benefit of much lower wing loading. With heavier birds, I would stick to something with more camber for sure.
Cheers
